As Scrooge's experience shows, this outcome will be dependent upon what one dedicates to these relationships.
Ironically, his nephew points out, Scrooge seems completely bereft of joy in spite of the fact that he is quite wealthy.
To his perspective though, this joy in the face of so much suffering is deserving of ridicule and even punishment. What's Christmas time to you but a time for paying bills without money; a time for finding yourself a year older, but not an hour richer; a time for balancing your books and having every item in 'em through a round dozen of months presented dead against you? 1) Here, it is notable that Scrooge does not simply speak with hostility toward others but even suggests that it may be the fault of others that he is so decidedly miserable.
By managing to yield increasingly more notable glimpses of humanity in Scrooge, Dickens keeps open the possibility that he might be saved through his personal relationships and, more generally, how he related to others throughout life.
Keeping this possibility intact also allows Dickens to keep the possibility intact for Victorian society.
